I've been looking for a movie that I can't remember the name but I know it first starts as a real movie then turns into a cartoon with a little girl named Molly Dot and that all I remember, does anyone know the name of the movie?

Around what year was this movie made in?

Did it have a Kangaroo in it - Might be this? The girl is called Dot, and it's cartoon over live background. No Molly though. Worth a shot...

Dot and the Kangaroo (1977)
